In a medium saute pan, saute garlic and shallots in canola oil until translucent. Remove from heat and cool. In a medium size bowl, whip together sour cream and Boursin cheese. When mixture becomes smooth, season with hot pepper sauce, Worcestershire, cilantro and chives. Finish with lime juice, salt and cayenne pepper to taste. Mix in crabmeat, garlic and shallots being careful not to break up the crabmeat too fine. Place crab salad on a piece of lavosh and serve as hors d'oeuvre.
